Installation Instructions Digital Expansion D-Shell Module CompactBlock LDX I/O (Cat. Nos. 1790-16BV0X, -8BV8VX, -8BV8BX, -0B16X, -0V16X, -0W8X) What This Document Describes This document describes how to install your CompactBlock LDX I/O expansion modules.
European Union Directive Compliance If this product has the CE mark, it is approved for installation within the European Union and EEA regions and it has been designed and tested to meet the following directives.
Installing CompactBlock LDX I/O Follow these steps to install the expansion module: 1. Mount the module. 2. Connect an expansion module to a base module. 3. Wire the D-Shell connectors. 4. Troubleshoot with the indicators. These steps are explained in detail in the following sections.
Panel Mounting 1. On the panel, position the module next to your previously-installed module. 2. Gently pull and position the expansion covers inward. 3. Place a center punch, nail or similar device through the mounting holes in the module (lower left and upper right corners of the module) and make two marks on the panel. 4. Remove the module and drill two holes in the panel to accommodate each of the mounting screws. 5.
DIN Rail Mounting 1. On the DIN rail, postion the expansion module next to your previously-installed module. 2. Hook the top of slot of the module over the DIN rail. 3. Pull down on the locking lever while pressing the module against the rail. f Locking Lever 4. Push up on the locking lever when module is flush against the rail. This secures the module to the rail . Connecting an Expansion Module to a Base Module ATTENTION Expansion modules should not be installed when power is applied to the base.
2. Position the expansion module with proper spacing.

C-UL and UL Hazardous Location Approval Due to the modular nature of a programmable control system, the product with the highest temperature rating determines the overall temperature code rating of a programmable control system in a Class I, Division 2, location. The temperature code rating is marked on the product label as shown.
The following warnings apply to products having C-UL and UL certification for use in hazardous locations. WARNING: Explosion Hazard Substitution of components may impair suitability for Class I, Division 2. Do not replace components unless power has been switched off or the area is known to be non-hazardous. Do not disconnect equipment unless power has been switched off or the area is known to be non-hazardous.
